To It whom/ zit mag concern;

Be it known that I, FRANK W. EDWARDS, a citizen of the United States, residing at Logansport, in the county of Cass and State of t Indiana, have invented a certain newand useful Improvement in Auxiliary Hand Oiling- Oupsfor Lubricators. of which the following is a full, clear, and exact description.

The primary object of this invention is to provide a hand oiling-cup as an auxiliar v to asight-feed condensation-displacement lubricatoradapted tobe used when the enginethrottle is open and whether the steam is on I a or oifthe main lubricator.

15 The invention comprises a lubricant-cup adapted to be applied to the upper feed-arm of a lubricator, the admission of steam to which cup for the purpose of discharging or feeding the lubricant. therein contained is controlled by valves and which cup communicates with thetallow-pipe or discharge-pipe 1 from thelubricator; all in the manner and for the purposes hereinafter more particularly set forth and claimed.

In the accompanying drawings, illustrating myinventiomin the two figures of which like parts are similarlydesignated, Figure 1 is a Ivertical section illustrating the parts closed. Fig. 2 is a similar section showing a modification inthe construction of the oil-cup.

The cup lmay be a casting, having a screwthreaded nipple 2, by means ofwbich it is secured toa portion of the upper feed-arm 3 ofan ordiharysight-feed lubricator. Within ,this tcup is arranged an internally-screwthreaded lug 4, having one or more openings I .5 atits base-thaws to say, at the bottom of thecupwhich lead intothe tubular nipple 2. .6fis a valve-seat in the upper portion of the cup, and Tie a drip-flange on top of the cup.

.fSfis a stemfhavijng hand-wheel e! other operatingdevice 9; This stem has a beveled portion 10, whichcooperateswith the valveseatand se'rVesas-ani let-valve for theintrocluction of lubrioan into the cup. The stern has a screw-threaded portion 11, which cooperates with the screw-threaded log 4.. This stem isprovided with a longitudinalpassage 12, having a lateral opening 13, commuseat'6, and then the valve 16 is opened.

open valve 16 admits steam up through the" PATENT OFFICE.

SPECIFICATION forming part of Letters Patent N 0. 723,149, dated March 17, 1903.

Application filed December 31, 1901. Serial No. 87,897. (No model.)

nicating with the interior of the cup 1. The lower portion 14 of this stem is of considerably less diameter than the internal diameter of the nipple 2 or is grooved longitudinally, so as to afford passages around the stem communicating with the openings 5 in the bottom of the lug 4. The passage 12 and the passages j around the portion 14 of the stem which communicate with the openings 5 also open into the feed-arm 3; but communication with the other portion 15 of the. feed-arm is controlled by a valve 16, seated at 17, and said valve may be secured in the feed-arm 3 byascrewthreaded connection 18 and operated by a hand-wheel 19.

i In the portion 15 of the feed-arm is arranged a check valve 20, which controls a port 21, opening into the coupling 22, with which the sight-feed glass is united. This check-valve is under the control of a screw-cap 23.

As shown in the modification, Fig. 2, the valve-seat. 6 may have an external upward continuation 24, with which the valve-stem may have a screw-threaded connection, and one or more holes 25 are made in this extension 24 at the bottom of the drip-cup 7, so as to provide for the entrance of oil in filling and the return into the oil-cup of any drippings that may collect in the said drip-cup.

The operation is as follows: The valve 16 is normally closed-when this auxiliary hand oiling-cup is not in use and the valve is opened. The cup 1 is then filled with oil, after which the valve 10 is tightly seated in its This passages surroundi ng the stem 14: and through through the passage 12 into the upper feedarm, and thence out through the continuation of said. feed-arm into the tall'ow-pipe.

- The check-valve is closed by the pressure in the feed-armand of course is so closed when the sight-feed glass is broken. As heretofore explained, this cup may be used when the steam is on the lubricator with the engine throttle-valve open, and it can openings 5 into the bottom of the oil-cup, and j .thereby displaces the oil and causes it to overflow through opening .13. and on down also be used when the steam is shut off, and it has been found to be a valuable auxiliary in maintaining the flow of lubricant in case of derangement of the main lubrieator and under other circumstances.

Of course I do not limit my invention to the single object statednarnely, as-an auxiliary tothe us'ual sight-feed lubricat0rbut wish to be understood as regarding the invention as an independent apparatus of wider application and mean so to be understood in claiming the invention.

What I claim is 1. An oil-cup, having a valve-seat at its top, and rising from its bottom an internally-serew-threaded lug provided with bottom openings into the cup, and a tubular exit-nipple at its bottom, and a valvular device cooperating with said valve-seat and lug to close the cup at top and bottom and including a stem having an internal lubricantdischarge passage, and external steam-passages on said stem opening communication between the lubricator feed-arm and the bottom openings, in the cup, combined with a lubrieator feed or discharge arm adapted to be connected with a steam-supply, and a valve for controlling communication between the said oil-cup andidischarge connections.

2. An auxiliary hand oiling-cup, for sightfeed lubrieators, comprising a cup proper having a valve-seat in its top, an externallyserew-threaded nipple 2, an internally-screwthreaded lug 4 arranged within the cup and alined with the nipple and having lateral openings 5 at the lower part of the cup, and

a valve-stem passing through the nipple and eator and a valve to control communication therewith, substantially as described.

In testimony whereof I have hereunto set my hand this 28th day of December, A. D. 1901.
